“开始地图”给我带来麻烦,我不知道为什么。
它说“锁定”和“解锁”不是myctrl的成员。
我找不到任何与之相关的东西,也找不到我需要对这两位成员做什么
我还得到一个错误:
Error 3 error C2660: 'CCmdTarget::InternalQueryInterface' : function does not take 4 arguments
对于MFC COM,您需要向
COleControl
派生类添加一些样板代码。警告-一些大的复制/粘贴即将出现,请原谅打字错误
首先,在控件的头文件中添加以下内容

END_INTERFACE_PART(ObjectSafety)

你混合了MFC COM和ATL COM,我不确定你会走得更远。请看一看。@RogerRowland这个控件曾经通过DllRegisterServer注册过,它工作得很好(链接中解释的第一个方法)。现在,我想将它从注册表中取出,并在IObjectSafety的控件中执行。但我不知道怎么做。我到底在混合什么?在VC++中进行COM有两种主要方法-一种是使用活动模板库(ATL),另一种是通过
COleControl
使用MFC。您使用了MFC路径,但您使用的链接仅用于ATL COM对象-完全不同的代码。我在回答中添加了一些MFC代码。谢谢。这绝对是一个进步。然而,一旦我继承了如下内容:classmyctrl:public COleControl,public IObjectSafety
,我就会从DECLARE\u DYNCREATE(myctrl)
和IMPLEMENT\u DYNCREATE(myctrl)
引发错误:错误1错误C2259:'myctrl':无法实例化抽象类
,因此我改为动态
,这解决了错误,但现在看来我的控制根本不起作用了。我无法用语言来形容你帮了我多少忙。我把ATL和MFC搞混了。这些代码都是从哪里来的?我想多了解一点。这个问题可能已经解决了,但老实说,这不是我开始的工作,而且我对该字段基本上一无所知。其中大部分内容似乎取自Microsoft的“SafeCtl.exe在ActiveX控件中实现IObjectSafety”示例-
